Libraries in 13 countries in Europe, the Middle East, and Africa—including several academic libraries in Spain, South Africa, Italy, the United Kingdom, Qatar, and others—have signed on to use Innovative Interfaces’ (III) in-development integrated library system (ILS), the Sierra Services Platform, the company announced today.

Numerous libraries have made agreements with III since Sierra was first announced last April. In October, III said that a total of 75 academic and public libraries in the United States and abroad had become early Sierra adopters.

Sierra, when first revealed at last year’s Innovative Users Group Annual Conference in San Francisco, was notable for potentially being more customizable than III’s current Millennium ILS. One feature announced as being in development, for example, is an online “Developer’s Sandbox” for testing new applications against its application programming interfaces (APIs).

The first development partners have received access to Sierra’s test systems, including its desktop application, according to the latest announcement. Sierra’s final release date has not yet been announced.

Among the newly announced Sierra libraries are the University of Bedfordshire, the University of Leeds, and the Wellcome Library in the UK; Universidad de Málaga, Universidad de Navarra, and Universidad de Sevilla in Spain; Università Cattolica del Sacro Cuore in Italy; and the Qatar Foundation Central Library.
